Key contribution

Thanks to its dynamic properties centered on energy efficiency and sustainable construction, SageGlass minimizes energy demand on buildings by reducing heating loads in winter, air conditioning in summer and electrical lighting all year long.


To recognise and encourage buildings designed to minimise operational Energy demand, Primary energy consumption and CO₂ emissions.

Requirement summary

This criteria recognizes improvements in the energy performance of the building above national building regulations in relation to heating and cooling energy demand, primary energy consumption and carbon dioxide emissions (using an approved building energy calculation software), Reducing energy demand has to be taken into account from the building design and/or through the systems specification.

Our contribution

During summer, blocking solar gain may reduce the load on buildings’ air conditioning systems. Conversely, allowing solar gain during winter will reduce the energy needed to heat the building. Thus, seasonal variation in combination with daylighting controls can deliver optimal energy performance of the glass facade with SageGlass glazing.
